Answer 1

Answer:

hope this helps you....

Answer 2

Answer:

I = Identity matrix

Step-by-step explanation:

Given that,

     | cos²x     sin²x |        +        |sin²x       cos²x|

     | sin²x      cos²x|                  |cos²x      sin²x|

⇒  |cos²x+sin²x        sin²x+cos²x|

    |sin²x+cos²x         cos²x+sin²x|

⇒  |1      1|                       (∵sin²x + cos²x =1)

     |1      1|

⇒  I =identity matrix

∴ | cos²x   sin²x|  +  |sin²x    cos²x|   = |1     1| =  I

   | sin²x   cos²x|     |cos²x     sin²x|     |1     1|

HOPE THIS WOULD BE HELPFUL FOR YOU
